Evaluation of sonic anemometers as highly sensitive optical turbulence measuring devices for the Thirty Meter Telescope site testing campaign

The Thirty Meter Telescope (TMT) site testing programme is evaluating the use of sonic anemometers as a means of measuring the optical turbulence at the level of its MASS/DIMM telescopes (7m). Tests were performed where sonic anemometers were directly compared against a differenced fine wire thermocouple system. We also show here that fine wire thermocouples produce turbulence measurements comparable to those from a traditional microthermal probe system

Sur la Mesure de la Constante Diélectrique des Liquides Conducteurs — II Cellule a distance inter‐électrode variable

A new cell is described here which can be used to determine the dielectric constant of conducting liquids or solutions in the radio‐frequency range. This new cell features a nearly coaxial structure (low self‐induction) and a variable distance between the two parallel electrodes (discs). The dielectric constant measured with this cell can be corrected for electrode effects according to Shaw's formula, without using extrapolation to infinite frequency or a method necessitating comparison to other conducting media. Measurements have been performed with aqueous electrolytic solutions. The results are compatible with those published previously and obtained by applying a different method of correction for electrode effects. It has thus been confirmed that the dielectric constant of extremely dilute solutions of strong electrolytes (c ≤ 3.10−3 moles/l) are very close to that of pure water.
